[Cryocoagulation in the treatment of bronchial tumors].

Abstract

From 1987 to 1989 22 men and one woman with morphologically certified tumors of the lungs were symptomatically treated with cryocoagulation. The cryoequipment KNF 4/5 with 30 W freezing capacity was used. After treatment in 20 out of 22 patients an objective improvement could be observed. A significant increase of spirographically measured vital capacity was found. Control observations of the results after treatment using a densitographic investigation of the regional distribution of the ventilation included the advantage that valuable informations concerning the effect of the treatment were received without further burden for the patient.
